Reland #2: Add a short term solution to fix OSX 10.11 system font rendering problems.

Reland #2: Add a short term solution to fix OSX 10.11 system font rendering problems.

The mechanism that Blink was using to determine OSX version number was not
reliable. This has since been fixed.

thakis: Please review.

Note that there is no change to the functionality since the original attempt to
land this CL. This CL just updates MacVersionUtilMac
